<pre>As part of <a class="bz_bug_link
bz_status_NEW "
title="NEW - WebAssembly: make code position independent"
href="show_bug.cgi?id=168264">bug #168264</a> to make WebAssembly position independent, we should migrate all state currently stored on VM to TLS instead. We have 4 slots to use so it could be a speedup to do this.
I'll start off simply moving the state, and afterwards we should be able to experiment with which fields should pointer-chase through TLS->instance->field, which should be in a TLS slot, and which should be in pinned registers.</pre>
